in antiquity, a crier, or officer appointed to publish something aloud, or call the people together. The word is formed from καλάω, voco, "I call." The pontiffs had such ministers, whom they used to send before them when they went to sacrifice on feriae or holidays, in order to advertise the people to leave off work. The magistrates also used calatores, to call the people to the comitia, both curiata and centuriata. The officers in the army also had calatores; as had likewise many private families, to invite their guests to entertainments.
